IMPROVEMENT in GRAIN-BINDERS.

Specification forming part of Letters Patent No. 179,058, dated June 20, 1876; application filed June 6, 1876. v 1

To all whom it may concern:

I Be it known that we, FRANK W. RANDALL and WILLIAM L. RAYMENT, both of'the village of Burlington, in the county of Calhoun and State of Michigan, have invented certain Improvements in Grain-Binders, of which the following is a specification:

Our invention relates to an improved twinebinding attachment for that class of harvesters which elevate the grain, the machine being hung to that part of the frame of the harvester to which the hand-binding platform is attached by means ofa rod passing through the frame of the binder; and it consistsin-the details of construction and'arrangement. of

I parts, all as Will behereinafter more fully dethe rear end of said shaft, as shown in Fig. 1,

while at the opposite end of the same shaft is secured a U-shaped cam, D, moving bar E and cam F, which engages with the frictionroller 1) upon the moving bar E, a also being a friction-roller situated upon the moving bar E, which engages with the U-shaped cam D. Near the rear end of said shaft A, and secured thereto, is a miter-gear, G, which operates the inclined shaft H. To the crank-cam O, at the rear end of the main driving-shaft, is connected the slotted pitman I, which operates the pivoted gathering-arm J, secured to the forward end of the shaft 0. The crankearn (J also operates the segmental swing-bar K, pivoted upon the frame B, by means of the friction-roller d, the flange e. engaging with the friction-roller f on said crank-cam G. The cylinder g, which carries the knot-tier p on its forward end, is rotated by the pinion h engaging With the said swing-bar K. The inclined shaft H is operated by a miter-gear cord.

shaft H, and, beneath the platform 0, which carries the knot-tying apparatus, is situated the double lug-shaped cam 19. Just above the platform 0, on the grabber m, is the frictionwheel Z, and at the extremeupper end of said shaft H is the U-shaped cam Q. The cam P operates the hook-bar R,whichpasses through the cylinder, by coming in contact with thefriction-roller situated on the spring-bar S. The grabber m is pivoted to the frame B, as shown at w, and is operated by the U-shaped cam Q at the extreme upper end of the inclined shaft H. w is a flat spring secured to the platform 0, and .connected to the arm of the grabber m in a suitable manner, said spring serving to keep the friction-wheel upon the grabber in close contact with the U-shaped cam Q. The grabber m is also provided with Y a sliding rod actuated by a coiled spring, the front part of said rod being provided with a suitably-shaped end for retaining the binding- The lower jaw of the shear S is stationary with the platform 0, while the upper jaw is operated by the friction-roller Z on arm l on the inclined shaft H, actuating the rod carrying the upper jaw of the shear, said rod moving in suitable guides, and provided with a coiled spring, which keeps the jaws of the shears open. The pivoted levert, in connection with the rod U, connected with the sliding rod of the grabber m, serves to open the jaws of the grabber to liberate the bindingcord. The binding-cord is guided to the knottier by suitably-shaped guides, as shown in Fig. 4;, and marked 1 2 3 4. The cams D and F, on the end of the main driving-shaft A, provided with friction-rollers, operate the U- shaped arm W by means of the segmental gear w. The arm W is provided with a slotted forked head of peculiar shape, and to the forward end is attached the compressing-cord as, which passes up through an eye opposite the head of' the knot-tier; from thence to an eye at the upper part of the standard y, and secured to the weight which slides, thereon. The function of said compressing-cord is to carry the bundle of grain from the bindingtable to the knot-tier, compressing the same in a compact manner, so' that after the knot is tied the expansion of the bundle will secure the band in position, the forks z serving to keep the bundle from becoming entangled with-the knot-tying mechanism.

Having thus described the construction and arrangement of the several parts of our improved invention, we will now proceed to describe its operation. The crankcam (J on the main driving-shaft A, turning in the direction of the arrow, operates the weighted lever T, by means of the slotted pitman I, which causes the pivoted gathering-arm J on the end of the shaft 0 to penetrate the falling grain and gather the bundle, moving it down the quarto-cylindrical table a against the binding-cord. Simultaneousl y with this movement, the friction-roller 70 passes oft thecam j, allowing the forked support m, by its own gravity, to move down ward, forming a support for the bundle, when the gatheringarm J has moved the bundle beyond the table a. At this juncture the forked head of the U-shaped arm NV passes beneath the bundle, and, catching the bindingcord, carriesitaround said bundle, and in asuitable position to be received by the grabber m, which holds the loose end of'the binding-cord, which passes through the head of the slidingfork support M, thence through the eye of the spring-bar n to the spool 0, upon which it is wound beneath the table u. The grabber 122. now. moves, carrying the cord into the head of the knot-tier p, when the hook R, by moving outwardly, confines the binding-cord in place. The knottier is now revolved by the swing-bar 70, causing the ends of the cords composing the band to cross each other, thereby forming a loop. The knot-tier, by a back turn of about a quarter of a revolution, causes the two ends of the cord to pass into the hook B. The cam Pon the inclined shaft draws the hook within the knot-tierp, and presses the ends of the cord against a pin in the-head of the knot tier. The jaw of the grabber now releases the loose end of the cord, and the continuous cord is secured in its place, and is moved within the shear S. The loop has now passed oii' the knot-tier p, the continuous cord being out within the shears, andithe horn on the head of the knot-tier beingturned downward, the loop slips off the horn, and the bundle drops to the ground securely tied, thus com 'pleting the operation.

Having thus described the construction and operation otour invention, we claim as new and useful- 1.
